Operation Dominic was a
36-detonation atmospheric nuclear test series. The first phase occurred
from 25 April through 11 July 1962, the second phase from 2 October
through 3 November 1962.

During the first phase, 24 nuclear weapons were dropped from aircraft
for air bursts in the vicinity of Christmas Island. One warhead was sent
aloft by rocket from Johnston Island for high altitude detonation, but
three attempted launches of nuclear tipped rockets from that island were
failures.

Shot Swordfish was an underwater detonation of a stock nuclear
anti-submarine rocket (ASROC) weapon approximately 370 nautical miles
west-southwest of San Diego. Shot Frigate Bird was the detonation of a
Polaris missile warhead over the Christmas Island Danger Area.

During the second phase, four nuclear warheads were rocketed from
Johnston Island for high altitude detonation, and one rocket launch was
a failure. Five weapons were dropped from aircraft for air bursts in the
vicinity of Johnston Island. This thermonuclear frenzy of superpower
saber-rattling was the end of US and Soviet atmospheric detonations.
